The wedding coordinator is a non-negotiable for me and the fiance, and it was also one of the hardest decisions we've ever made with regards to our wedding. Having been to so many weddings where things went awry (some only slightly, some totally phobia-including), we knew we couldn't do it ourselves. We also didn't want to rely on our friends and family - we want them to enjoy the day with us, and not have to worry about anything. Our college friend Jason also gave us very good advice. He said that it's different when people are paid to do something, and we totally agree with him.
